Precision quantum simulation of magnon spectra and interactions
Trond I. Andersen, Nikita Astrakhantsev, Jeronimo Martinez +329
Quantum simulation promises to advance materials discovery by accurately simulating complex states of matter, their microscopic excitations, and macroscopic response functions. The…
Multifractal and Glassy Signatures of Non-Ergodic 2D Quantum Dynamics
Aleksey Lunkin, Nicole S. Ticea, Michael T. Solomon +296
The fate of ergodicity and localization in disordered, interacting quantum systems in two spatial dimensions remains an outstanding open problem in non-equilibrium physics. Theoret…
Exceeding the Parametric Drive Strength Threshold in Nonlinear Circuits
Mingkang Xia, Cristóbal Lledó, Matthew Capocci +7
Superconducting quantum circuits rely on strong drives to implement fast gates, high-fidelity readout, and state stabilization. However, these drives can induce uncontrolled excita…
